1 The Thunderbird story Peter Dauvellier and Marco de Vries March 2018 / Grou / The Netherlands

2 A beautiful disaster Many years ago I got interested in the series of Mini Dinky s, manufactured in the late sixties. As a child in the fifties I was already an enthusiastic Dinky Toys player and collector. Many years later I tried to please our sons with my old Dinky Toys, refurbished by myself in beautiful colors. They were not very excited about second hand toys without any speedwheels. So for many years my collection was down in a box, waiting for better times. The internet gave me the opportunity to refind a lot of old Dinky Toys and information behind. I learned that two of them were produced in Holland, my home country: the nr. 60 Cooper and the nr. 61 Lotus. However, they were made on scale 1/65 and not the usual 1/43. This series of Mini Dinky s had a very particular history. They were introduced to match with the modern and speedy small models of Mattel Hot wheels and Matchbox Superfast. But: although beautiful in design and detail, the Hong Kong producers used inferior construction materials (Zamak). On top of that the beautiful but fragile features of opening doors and hoods were far too vulnerable for children's hands. So the whole series ended as a commercial disaster and marked the end of Meccano, the brand that at that time was owned by Tri-ang and part of the big Lines Bros company.

3 The find of a treasure The series of Mini Dinky were interrupted and many of the just recently announced 18 more cars soon were never taken into production. All together this meant two important things for an interested collector: - complete models with in good condition are hard to find - the mystery of which models and which colors were actually produced left many open questions. It made me curious: looking around and buying a few nice items. I must say that if you are lucky to find some items that are kept well and are in good order, they are real gems. And as all dedicated collectors know: if the fire starts burning you want to find them all, and in the best possible shape you can get, even if it takes you years and years of searching. In this finding mood I was completely surprised by an advertisement on Ebay in January Andy Wooler (nickname: Ziggeystardust ; yes: spelled with an extra e ) offered a series of preproduction models of Mini Dinky for sale. Some were known from the come soon list but never been produced, or were shown in colors that had not been seen before.

4 But even more surprising was that three cars were completely unknown numbers and brands: never before mentioned in any article or collectors guide!! They were: nr. 35 Rambler Ambassador, nr. 36 Ford Thunderbird and nr. 37 Chevrolet Camaro. Of the Rambler and the Camaro there were incomplete and unpainted unique models on offer: the only example known to exist. Of the Thunderbird there was no body, only a set of technical blueprints. All this was found by Andy on an auction of furniture and belongings of a former Lines Bros employee. Of course the interest of collectors was intense. Of course I was bidding as high as I could go on several items. I went far over any amount I had spent before and with some great wins! At the end I was the proud owner of some unpainted and unpressed preproduction models. But above all I had what I wanted most: the complete set of eight blueprints of the nr. 36 Ford Thunderbird. In my view the most attempting mystery catch of all the treasures in this lot!

5 A crazy dream When the cars and drawings arrived they were just beautiful to look at and to imagine how they were made by the dedicated designer and craftsman: G.F. Hammond from Lines Bros ltd. Due to the fact that the Zamak pre-pro models were made in Great Britain they did not suffer the poor quality of many of those made in Hong Kong. And mr. Hammond s drawings were magnificent in detail and accuracy. Drawn on a 4:1 scale and full of the measures and guidelines, they certainly were made to be manufactured, even though they were not mentioned before in any advertising campaign or catalogue. The first thing I did was to have a professional copy firm make scans of the whole set of eight drawings, just to save this piece of history for the future. It felt very special: owning blueprints of a Dinky Toys that never had been made! You could compare it with finding the complete DNA of a fossil animal extinct long ago. But even that animal had been real at some time, this Dinky Toys had not, yet! The crazy Jurassic Park thought entered my mind: could it be possible to make this beautiful design come to life? Could a mold been made of it and a cast in Zamak? I searched the internet, but did not find solutions, although I learned some things about the production process. It just seemed a crazy dream.

6 Images of what could be Well, so be it, but being a designer myself I could do something by creating some semi-realistic drawings based on the scans. It seemed a first step, but at the same time the end of this short adventure. In a way I felt like making the dream come true a little and pay tribute to the unknown Mini Dinky nr 36. At least the Dino got a face now.

7 Yet it appeared to be not the end of the story. Showing my blueprints proudly to some friends a new idea came to mind. Would it be possible to construct the car using a 3D printer? A young friend of ours, Marco de Vries, was working with professional 3D printers as part of his studies. And I knew he also was interested in car models, especially those of Formula 1 Champions over the years. So I showed him what I had and dreamed of. He was positive about this idea and suggested to make a test print of one of the body parts. But first of all he had to put the detailed drawings in a 3D design program named SolidWorks. That was a real big job! The first problem he had to cope with was the lack of measurements in the blueprints. Some measurements had to be calculated, others were drawn in different drawings and some were missing. The second problem was the usage of inches (x1000). To get to mm he had to multiply the numbers by 25,4 and divide them by Eventually Marco was able to finish the first two parts in SolidWorks and virtually assemble them together in the program! When all the 3D-designing was done, it was possible to create a 3D preview of the model. In this way could be tested if everything fitted well and at the same time create a preview on the possible result. The colors green and black we borrowed from the 1/43 Dinky Toys 1419-F Ford Thunderbird made in 1969.

8 First 3D print Could we really make it happen after all? The first test peace made on a Stratasys uprint SE Plus FDM 3D printer was the interior part. The piece was made from the strong plastic ABS. It worked, but certainly showed that the printer had to operate to the limits of its abilities (the minimum layer size was 0,254 mm or 1/100 ). That is why we decided not to print on a scale of 1/65 like the other Mini Dinky s, but on 1/50. On this scale we were able to make even the rib structure of the seats fabrics visible! All the parts were printed, but the roughness of the print layers was still visible. By using acetone it was possible to melt the layers together to create a nice, smooth surface. After printing all the parts we bought four tires and used metal pins for the axles. I sprayed the body and painted the other parts by hand. Now the question was: will they all fit together? Fine hand skills were needed to find the right assembling order. Finally it worked. Only the doors missed a small axle on the upper side. But that was all, the rest fitted quite well for a first issue. Of course we were eager to see the bottom plate with the very small lettering on it. That would be the ultimate proof that nr 36 was meant to be produced! The main characters were readable. Unfortunately the printer could not cope with the smallest lettering.

9 Still: here it was, the first pre pro Mini Dinky Thunderbird. All of the parts were made from the blueprints, except the wheels, axles and tires. To celebrate this I created a new series: the Midi Dinky scale 1/50 but with the yellow box, certainly family of the Big Brand.

10 A new attempt The job was done, almost.. Because we still had some wishes that we would be very anxious to fulfill. On top of the list was the wish to print a base plate with visible lettering. And secondly: to print on the original scale of 1/65. We kept searching, and after some months we thought Marco had found a 3D printer that could handle the fine lettering. In fact it gave a very promising result! Soon we were pulled back with our feet on earth and found that there are other obstacles to cross. The Formlabs Tough resin was not stiff enough, the bottom and other parts bowed in different directions. Again we experienced the borders of technical resources that were within our reach. Maybe we wanted too much? We slowed down our efforts for many months, knowing/hoping that time was on our side. In the meantime Marco perfected the 3D drawings to the detail, using photo s and existing 1:43 models. The Thunderbird got its very smooth curves in the computer, waiting for a chance to get shaped on scale in 3D reality.

11 The Final break trough After more than a year we got a new chance. Marco spotted two firms with useable professional 3D printers. Both of the them had a lot of experience in small detailed 3D printing. VDM Kunststoftechniek used our model to test their Envisiontec Ultra printer. Good for us, because they were so kind to send us the two test prints for free! And these models were very accurate, stiff enough and showed all the text. But even slightly better was the product of the second new printer, the 3D Systems Project HD 3500, owned by Shapeways. This printer uses the material jetting technique, which works in the same way as ink printers, but in 3D. Hood, trunk and doors are fitting perfect, even better than in any Zamak model! And still the parts open easily. The text on the bottom is as sharp as possible. This was what we had in mind and were waiting for! I sprayed the body and painted the interior and base plate. From an old Mini Dinky Olsmobile Comodore I borrowed the axes and wheels. I transformed an old Mini Dinky garage for this occasion. And here is the old new Mini Dinky 36 Ford Thunderbird in all its glamour!

13 Epilog The newborn member of the Dinky Family is happy to join this famous party. Here we see him with his 1967 uncle on 1/43 scale. And of course the Mini Dinky nr. 36 will try to claim its place in the glorious history of the Big Firm. It is well aware that its (not) being marked the end of the glorious Dinky Toys story. Its conception was the last effort to survive for Dinky Toys, but with no success. until now. The unbelievable craftsmanship of this little car model shows what men are able to create just for fun! Side by side with big Dinky brother no: 1419 In this respect nr. 36 feels very much related to other beauties of die cast history. For instance his Top Gear cousin. Although this very scarce model has no opening doors, it is a very close related family member. With its speed wheels, it tried to fight the battle with Mattel en Matchbox. It did not win, but today its value is 100 times the value of these common models. And its shape and number reveals its famous roots: 136. We are proud to give this small car model a face and body as a tribute to the great designers and manufacturers of Meccano. Very close cousin Top Gear no: 136 The four stages of revival together
